The hardness of the wire refers to the malleability. Hardness also differs by material. Sterling is harder than copper. Brass and bronze tend to be stiffer than both copper and sterling. When youâre working with very fine gauges, hardness is a bit irrelevant, since fine gauge wires are so thin and pliable.
Steel is cheaper, and brass is more expensive, and not much of a structural material. Brass is a tensile metal, and has a great ability to bend. It is used to make bearings, valves and moving parts, because it does not break easily. Steel, on the contrary, is difficult to cast, and quite difficult to work with in small machines.
